Definitions

  • the present invention is directed to a white snus comprising a filler material, a nicotine source and flavoring.
  • the flavoring comprises tobacco particles having a size (sDso laser diffraction) ⁇ 30 pm adhered on an inert carrier.
  • a method for producing a white snus comprising the steps of providing filler material, providing a nicotine source, providing tobacco particles having a size (sDso laser diffraction) ⁇ 30 pm adhered on an inert carrier, providing further flavorings, optionally providing further ingredients and mechanically mixing the ingredients is described.
  • Snus is a smokeless tobacco product which is usually consumed by placement inside the lip between the lip and gums for an extended period.
  • (Brown) snus usually comprises tobacco composition in a pouch. Often the tobacco composition is prepackaged as moist powder in small teabag-like sachets. Snus is often mildly flavored with food-grade bergamot, citrus, juniper berry, herbs and/or floral flavors, as described in US 2012/0055494 A1. In contrast to snuff, the snus tobacco is usually not fermented. In its traditional form, the sachet material is moisturized during the manufacturing process. This results in a brownish appearance of the pouch.
  • the brownish pouch is often considered to appear unhygienic, so-called white snus have become popular.
  • the white snus is usually a milder-tasting and slightly slower-release form.
  • the main difference with respect to the traditional form is that the sachet material is not moisturized during the manufacturing process.
  • the pouch remains dry and discoloration due to diffusion of coloring agents through the pouch material is slowed.
  • nicotine pouches, which are not containing tobacco leaves are considered to be white snus.
  • a white snus according to the invention comprises sachet material, preferably a pouch, which is not moisturized during the manufacturing process. Furthermore, the white snus comprises a filler material, a nicotine source and flavoring.
  • the flavoring comprises tobacco particles having a size (sDso laser diffraction) ⁇ 30 pm adhered on an inert carrier. Surprisingly, it has been found that tobacco particles having such a small size and adhered to the surface of a carrier material are causing less or even no discoloring of the pouch (and/or the user’s teeth). Because of the small size, the particles are not visible to the human eye, at least through the pores of the pouch. Furthermore, the small particles have shown to deliver the full tobacco flavor to a user. The full tobacco flavor could be even provided very quickly.
  • the tobacco particles may originate from any part of the tobacco plant, e.g. leaves, stems or roots.
  • the nicotine source may be tobacco, but the invention is not limited to white snus comprising tobacco as (main) nicotine source.
  • the tobacco of the nicotine source differs from the kind of tobacco used for producing the small tobacco particles. Since the tobacco flavor is mainly provided (and determined) by the flavor of the small tobacco particles, a cheaper tobacco quality could be used for the nicotine source.
  • inert especially in combination with the word “carrier”, means in the context of the present invention, that a first substance does not chemically interact with the second substance (e.g. the carrier).
  • An inert carrier is preferably inert with respect to the surrounding environment.
  • the carrier itself remains chemically unchanged when contacted by other components of the snus, e.g. the nicotine source or the pouch material.
  • inert does not mean that no interaction between the other components and the (inert) carrier is possible.
  • Especially physical interactions like energy transfer is possible.
  • other physical properties of the inert material e.g. the carrier
  • the average size of the tobacco particles is > 1 pm, preferably > 2.5 pm, more preferably > 5 pm, most preferably > 8 pm. It has been found, that grinding of the tobacco particles to a smaller particle size could affect the flavor. It is believed that some of the flavoring molecules of the tobacco decompose during the grinding process due to the high shear energy. Furthermore, some flavoring molecules could exit too small tobacco particles during the grinding process or during a later handling process. This would result in a depletion of these flavoring molecules in the tobacco particles and a flavor different with respect to the full tobacco flavor. Furthermore, it has been found, that larger particles could maintain the full tobacco flavor over a longer period during consumption of the snus.
  • Tobacco particles having such a small average particle size are providing a high surface area from which flavoring molecules could leave the particle.
  • the particle size of ⁇ 30 pm has been found to allow transfer of a plurality of flavoring molecules homogeneously over a long time period. Thus, a full tobacco flavor could be maintained over a long period.
  • the particle size allows migration of bigger and smaller molecules from an internal volume of the particles to their surface from which these molecules could exit and then be tasted by a user. It has been shown that the mean size of the tobacco particles provides an optimal volume to surface ratio, due to which a mixture with widely constant ratios of flavoring molecules leaves the particles over a long time interval.
  • the snus preferably comprises a nicotine source other than tobacco leaves.
  • the nicotine source does not contain tobacco.
  • the snus does not contain tobacco leaves and more preferably the tobacco particles having a size ⁇ 30 pm adhered on an inert carrier is the only tobacco compound of the snus. Due to the corresponding reduction of the total tobacco content, high taxes or restrictions could be avoided.
  • the amount of dry the tobacco particles is less than 2 % (weight/weight) of the dry snus, preferably less than 1 %, more preferably in the range of 0.01 to 0.1 %. All the previous mentioned percentages are defining the dry weight of the tobacco particles with respect to the dry weight of the entire snus, including the pouch.
  • dry in this context means, that the weight percentages refer to the dry weight only without any liquid components. Also in the following, any percentages should be understood in this manner, if not explicitly specified differently. It has been shown, that an amount of the tobacco particles in the above- mentioned rage is high enough to provide the full tobacco flavor over a long period. On the other hand, these amounts of the tobacco particles are small enough to reduce or even avoid discoloring of the pouch. Thus, the appearance of the snus remains hygienic.
  • a form of the carrier material is selected from a group comprising fibers, filtering material, fiber tow, staple fibers, randomly oriented staple fibers, sheets, paper sheet, folded paper, rolled paper, crimped paper, matrix material, sponge type, ceramic material, fleece, multiple tubes, single tube, granulate, spherical particles, cubes, cuboids and parallelepipeds.
  • the tobacco particles are adhered to an inert carrier comprising cellulose.
  • cellulose is a natural product which is frequently used in tobacco industry, it is well tolerated by the user, has no or only little influence on the flavor and could be handled in large quantities with handling machines known in tobacco industry.
  • the carrier comprises cellulose fibers, powders or granules (or combinations thereof). These forms could be produced and handled easily. Due to the fiber structure of cellulose, a clear differentiation between the terms “fiber”, “powder” and “granule” with respect to cellulose products is difficult and often only depends on the length of the fiber (of given diameter).
  • a fiber should be understood as a particle having a longitudinal extension which exceeds its extension in the width and height direction by a factor of > 20, preferably > 50, more preferably > 100. All these forms of cellulose provide a large surface area (with respect to its volume) which allow adherence of tobacco particles. Thus, the overall density of tobacco particles could be high. This has been found advantageous for delivery of the full tobacco flavor.
  • the tobacco flavor could reach the surface easily and exit the particle.
  • the tobacco flavor is extractable from the tobacco particles adhered on the inert carrier by saliva. This embodiment is preferred since undesired loss of flavor during storage could be limited.
  • releasing of the flavoring molecules from the tobacco particles is initiable by an activation signal.
  • the activation signal is selected from a group comprising temperature change, mechanical strain, humidity change, change of the pH value, contact to a liquid, contact to water and contact to saliva.
  • the extraction of the flavoring molecules from the small tobacco particles is initiated by one or more proteins of the saliva.
  • the tobacco particles remain adhered to the inert carrier when contacted by saliva.
  • the amount (weight) of the nicotine source in the snus is at least 5-fold, preferably > 7-fold, > 10-fold or even > 20-fold higher than the amount of the small tobacco particles. It has been found, that even small amounts of the small tobacco particles are suitable to provide the full tobacco flavor to a user, even if large amounts of the nicotine source are present. The above-mentioned ratios are preferred since a cheap and/or tobacco free nicotine source could be used and the full tobacco flavor could be maintained anyway. High ratios between the amount of the nicotine source in the snus and the amount of the small tobacco particles are especially preferred if legal restrictions or high taxes limit the acceptance of tobacco leaves as nicotine source in the snus product.
  • the tobacco particles adhered to the inert carrier are obtained by grinding of a tobacco source.
  • the tobacco particles comprise chemically metastable flavoring molecules. More preferably the grinding process is performed at reduced temperature of ⁇ 15°C, preferably ⁇ 12°C, more preferably a temperature of 0° to 10°C. The lower temperature avoids decomposition of favoring molecules during grinding.
  • a solvent or “dispersion medium” is preferably selected from a group comprising water, monovalent alcohols, polyvalent alcohols, sugar alcohols, sugars and polyvalent alcohol esters.
  • the one or more dispersion medium is selected from a group comprising water, monovalent alcohol, monovalent aliphatic alcohol, methanol, ethanol, 1-propanol, 2- propanol, 1-butanol, 2-butanol, 2-methyl-1 -propanol, 2,2-dimethylethanol, cyclohexanol, monovalent alcohol having an aromatic substituent, benzyl alcohol, monovalent alcohol containing one or more halogen element monovalent alcohol having one or more ether bond, polyvalent alcohol, glycerol, propylene glycol, sugar alcohol, sorbitol, maltitol, xylitol, erythritol, lactitol, sorbitan, xylose, arabinose, mannose, trehalose, sugar, lactose, sucrose, coupling sugar, glucose, enzyme-saccharified starch syrup, acid-saccharified starch syrup, maltose starch syrup, maltose, isomer
  • the ratio of the tobacco particles in a grinding dispersion is > 0,5 % (w/w), preferably > 1 % (w/w), > 2 % (w/w) or > 5 % (w/w), more preferably > 10 % (w/w), most preferably > 20 % (w/w) and ⁇ 95 % (w/w), preferably ⁇ 90 % (w/w), ⁇ 80 % (w/w) or ⁇ 70 % (w/w), more preferably ⁇ 60 % (w/w), most preferably ⁇ 50 % (w/w). It has been found that these ratios allow grinding of the tobacco to the desired average particle size in most of the solvents without significant loss of flavor.
  • the snus comprises further additives.
  • the snus comprises at least 2, preferably > 3, more preferably > 4, more preferably > 5, more preferably > 6 further substances.
  • these additives are selected from a group comprising a filler material, water, humectants, cellulose, glycol, propylene glycol, glycerol, sweetener, sugar, sugar alcohol, gum, pH-adjusting agent, puffer agent, ammonia, ammonium carbonate, potassium carbonate, sodium carbonate, calcium carbonate, preservative, salt.
  • the water content of the snus is affecting diffusion of coloring and/or flavoring molecules through the snus composition. This diffusion may result in loss of flavor and/or discoloration of the pouch.
  • the water content of the snus is >15 % and preferably in the range of 15 - 70 % (w/w), more preferred in the range of 20 - 65 %, most preferred in the range of 30 - 60 % or.
  • the given weight percentages refer to the whole snus excluding the pouch. It is however preferred to apply the invention to a dry snus. Dry snus comprise an overall water content of less than 15 %. In dry snus the problems related to diffusion will not occur due to the low water content.
  • the tobacco particles are pasteurized. This could increase the shelf life of the snus.
  • the sterilization (the terms “pasteurized” and “pasteurization” are used synonymously with the terms “sterilized” and “sterilization”) follows the grinding process.
  • the sterilization process is performed at elevated temperature. The higher temperature could be used to get rid of the solvent (or dispersion medium) added during the grinding process.
  • the sterilization process could also include the process of adhering the tobacco particles on the carrier.
  • a further aspect of the invention is a method for manufacturing a white snus comprising the steps of: providing a filler material, providing a nicotine source, providing tobacco particles having a size ⁇ 30 pm adhered on an inert carrier, providing further flavorings, optionally providing further ingredients, mechanically mixing the ingredients.
  • This method allows production of a white snus in an easy manner, which provides a desired tobacco flavor even if this tobacco is not the main nicotine source.
  • this method allows selection of a desired tobacco flavor independently from an eventually present flavor of the nicotine source.
  • Even snus compositions which originally do not provide a tobacco flavor e.g. because the nicotine does not derive from tobacco, could be adjusted easily to provide a desired tobacco flavor.
  • the tobacco particles adhered on the inert carrier are added to the mixture of all the other ingredients during mixture of all other ingredients.
  • This variation of the method allows adjustment of the properties of the snus composition independently from its flavor.
  • properties of the composition selected from a group comprising water content, moisture, viscosity, temperature, and pH value are set to desired values prior adding the tobacco particles adhered on the inert carrier.
  • an intermediate composition is prepared by adhering the tobacco extract on an inert (preferably solid) carrier material.
  • the intermediate composition is prepared by adhering the tobacco particles on the inert carrier material.
  • Such an intermediate composition could comprise further components (or ingredients). Preparing an intermediate composition has been found advantageous, since it could be produced in large quantities and stored over a long period (preferably at gas tight conditions). The same intermediate composition could be used for a plurality of batches of snus compositions. This ensures a (identical) high product quality for a plurality of different batches of snus products.
  • Adding the tobacco particles adhered on the inert carrier during a very late handling step reduces the risk of loss of flavor or decomposition of flavoring molecules due to following handling steps.
  • the tobacco particles adhered on the inert carrier is added to the mixture of the other ingredients in an amount of less than 2 % (weight/weight), preferably less than 1 %, more preferably in the range of 0.01 to 0.1 %.
  • weight/weight preferably less than 1 %, more preferably in the range of 0.01 to 0.1 %.
  • Usually such a little percentage of the tobacco particles adhered on the inert carrier does not change the properties (e.g. water content, viscosity, temperature, and pH value) of the snus composition much.
  • the method further comprises the step of pasteurizing the tobacco particles adhered on an inert carrier.
  • This step is preferably carried out independently from other ingredients of the snus composition.
